The cylinder is made of cast iron and has 6 transfer ports and a simple oval exhaust port. Cast iron cylinders are reliable and powerful and an affordable alternative to pricier aluminium cylinders. It comes with a 2-ring piston, the monobloc cylinder head is made of aluminium. Also includied is a gasket kit with all the gaskets you need for mounting this cylinder.

Powerful and durable at the same time, this top quality cylinder will boost performance and last you a long time. To exploit the full potential of this kit, we recommend combining it with a minimum 17,5mm – 21mm carburetor and a sports / mid-race exhaust (such as the Stage6 Pro Replica), or a racing exhaust for higher rpms (we recommend the Yasuni R); with the right set-up, this kit can produce 10 – 13hp, with maximum speeds around 10,000rpm.
